10 MINIATURE CIRCUIT BREAKER Construction Miniature Circuit Breakers have precisely formed moulded case & cover of flame retardant high strength thermo-plastic material having high melting point, low water absorption, high dielectric strength and temperature withstand. The Switching Mechanism is independent, manual and trip free, i.e., the breaker trips internally even if the operating knob is held in ON position. The Contact Mechanism comprises of fixed & moving contacts specially designed for reliability, long life and anti-weld properties. The Arc Extinguishing Device comprises of 13 plates arc chute. The arc under the influence of the magnetic field and arc guide is moved mechanism is Thermal Magnetic Type. Thermal Operation The thermal operation provides protection from moderate overloads. Under overload condition, a thermo-metallic element (bimetallic strip) deflects until it operates a latching mechanism allowing the main contacts to open. Magnetic Operation In magnetic operation, large overloads or short circuit current actuates a solenoid causing a plunger to strike the latching mechanism rapidly opening the main contacts.

15 Short Circuit Currents The maximum short circuit current possible on a DC system is determined by the voltage of the battery and the total internal resistance of the cells. Where, I sc is the Short Circuit Current V b R b is the internal resistance of the battery cells (this is usually stated by the manufacturer) Technical data Correct polarity connections for DC MCBs B _ Double pole MCB + Circuit Time Constant inductance of the circuit R is The Resistance Of The Circuit The time constant is usually given in milliseconds (ms.). Ideally, DC circuits would be mainly resistive (i.e. a low number), as inductive circuits produce a back emf when the current suddenly falls. This in turn tends to prolong arcing during switching operations, and so reduce contact life. + DC supply + + DC supply Circuit Voltage The voltage of the circuit is dependent upon the power supply. The lower the voltage the easier switching operations will be, but the voltage makes no difference to the running of the MCBs. Contact life can be significantly increased by reducing the voltage, drop across each pole. This can be achieved by wiring poles in series.

29 electrical device can cause current to flow through the wrong path (i.e. through the insulation/human body) to the earth. RCCB (also popularly known as ELCB) is a mechanical switching device designed to make, carry and break currents under normal service conditions and to cause the opening of the contacts when the leakage current attains a given value under specified conditions. fire caused by earth faults. Features connection Product Range 16A - 63A Sensitivity 30mA, 100mA & 300mA Execution Double Pole (2P) Four Pole (4P) Specification IS Part 1/ IEC / EN Safety Terminals To avoid improper cable termination, the safety terminals guide the cable towards the cage terminal for systematic termination Large Cable Terminals Suitable for copper and aluminum cables, these terminals are compatible with cables upto 35mm 2 cross section area Bi Stable Clip Every device is provided with a dual position DIN rail clip, so it becomes much easier to change a device from a device bank connected to a bus-bar, without disturbing the existing wiring Cooler Operation Grooves provided on outer body, so that when individual poles are placed adjacent to each other in a distribution board it forms a very effective channel for better air circulation, resulting into a cooler operation 29

30 RESIDUAL CURRENT CIRCUIT BREAKER (16A - 63A) The use of exposed, substandard, badly wired, wrongly connected reduces the safety of an installation and increases the risk of person receiving an electric shock. RCCBs are electrical devices which afford a very high degree of protection against the risks of electrocution and fire caused by earth faults. Protection Against Electrocution Electrocution is a passage of current through human body, which is dangerous. The flow of current through human body affects vital functions of breathing & heartbeat. Effect of electric current through human body has been well 500 ma Immediate cardiac arrest resulting in death ma Cardiac fibrillation; the heart begins to vibrate and no longer beats at a steady rate. This situation is dangerous since it is irreversible ma Muscle contraction can cause respiratory paralysis 10 ma 1-10 ma Prickling sensations alone, but in terms of contact voltage. A person gets electrocuted by coming in contact with an object that has a different potential from his/her own. The difference in potential causes the current to flow through the body. - Under normal dry conditions, voltage limit = 50V - In damp surroundings, voltage limit = 25V A correctly chosen RCCB can detect small currents flowing to earth and reduces the risk of electrocution. Protection Against Indirect Contact Over current protection devices like MCB are unable to act promptly on small earth leakage currents. To comply with wiring regulations, the earth fault loop impedance in Ohms, multiplied by the rated tripping current of the RCD in amperes must not exceed 50. Example For an RCD with a rated tripping current of 30mA, the maximum (max) = 50 / In = 50/0.03 = 1,666 Protection Against Fire The majority of fires which occur as a result of faulty wiring are started by current flowing to earth. Fire can be started by fault current of less than 1 amp.the normal domestic overload protective device such as a fuse or MCB will not detect such a small current. A correctly chosen RCD will detect this fault current and interrupt the supply, hence, reducing the risk of a fire starting. Rated Tripping Current of the RCD Maximum permissible earth fault loop impedance in 10 ma 5, ma 1, ma ma

31 Working Principle The RCCB works on the current balance principle. The supply conductors, i.e. the phases and the neutral, are passed through a toroid and form the primary windings of a current transformer. Its secondary winding is connected to a highly sensitive electromagnetic trip relay, which operates the trip mechanism. flows to earth, the currents do not balance and their vector sum is current transformer, the RCCB is tripped and supply to load is interrupted. The trip mechanism is operated at a residual current Zone Zone 1 Zone 2 Physiological Effects Usually no reactions Usually no harmful physiological effects Zone 3 Usually no organic damage to be expected. Likelihood of muscular contraction and difficulty in breathing, reversible disturbances of formation and conduction of impulse in the heart and transient cardiac arrest without ventricular fibrillation increases with current magnitude and time. Zone 4 probability if ventricular fibrillation 2 ) upto 3 beyond curve C3. It increases with magnitude and time, and pathophysiological effects such as cardiac arrest, breathing arrest and heavy burns may occur. 31

32 RESIDUAL CURRENT CIRCUIT BREAKER (16A - 63A) Sensitivity Selection 30 ma A 30 ma RCCB will provide a high degree of protection against flowing through human body could be between 80mA and 240mA depending on the resistance of the human body and the voltage across it. to operate within 50ms at 240 ma and 150ms at 80mA. Both these conditions are satisfied by 30mA RCCB. For households, individual outlets, wet areas and temporary installations, RCCB with sensitivity not exceeding 30mA is advisable. 100 ma A 100mA RCCB will normally give high degree of protection against electrocution but there is a possibility that the shock current could fall below the tripping level of RCCB. This could occur if additional resistances to that of human body are included in the earth path. The 100mA RCCB protects against leakage currents and indirect contact with earth loop impedance up to 500 Ohms. 300 / 500mA A 300/500 ma RCCB may be used where only fire protection shock is small. 300/500mA RCCB will not give any protection against electrocution. Selection of RCCB Type RCCB Type AC AC Type RCCB are used for residual sinusoidal alternating current. RCCB Type A A Type RCCB is used for residual sinusoidal alternating currents and residual pulsating direct currents, whether suddenly applied or slowly rising. It can therefore handle the residual current waveforms which can occur in the power supply units of single-phase loads with electronic components (e.g. ECG, dimmer switches). This type of residual current protective device is suitable for electronic Actuation Time Characteristics 500 Time (in ms) Residual Current Multiple of IΔn (ma) 32

79 TPN ACCL They are available in two versions Basic and Compact to meet the varying needs of users. TPN ACCL Compact TPN ACCL FUNCTIONS 1. When mains supply is available The device will run the load on mains supply if the R phase is available irrespective of the availability of all other phases. It is recommended to connect the entire essential load to R phase. 2. When mains supply fails If mains supply goes off (detected by R phase), the device will automatically sense and actuate the inbuilt changeover mechanism to the generator supply. This takes 8-12sec so as to avoid sudden loading on generator. TPN ACCL also allows user to opt for manual mode for manual transfer of load to gen-set. Current Limiting feature on Generator side: If load current exceeds the preset allowable limit, then Overload LED will start glowing, but load will remain connected for 5 sec to ignore the surge current. But if load still persists beyond the preset limit, it is disconnected for 8 sec as a warning and then automatically reconnected. Such cycle of interruptions continue for a number of times during which the user is expected to switch off nonessential loads. 3. When mains supply restores On resumption of mains, the load is automatically transferred to main supply after a time delay of 2-4 sec.

130 PHASE SELECTOR DISTRIBUTION BOARDS Automatic Phase Selector DB The power instability in developing countries creates the need for phase selection to back up the utility supply. Today there is a growing need of automation in distribution system as the rate of power outage and low voltage output becomes predominantly high. Automatic Phase Selector DBs offers several advantages over manual phase selector DBs. Most of the residential and commercial applications are dependent on power supply and if the process of changeover is manual, a considerable time is wasted, and it may also cause hindrance in important activities. Moreover manual changing is not possible every time as identifying the phase of power interruption is difficult. In addition to above, this DB introduces an automatic solution to overcome problems of not just phase outage but also power fluctuations (over-voltage/ under-voltage) by selecting the next most healthy phase available. It maintains a constant output power supply irrespective of the available input supply by continuously monitoring each phase, automatically switching between them and returning to the priority phase as necessary. The phase priority selection is manually carried out by the user through a priority selector switch present on the front facia of Automatic Phase selector. The user can rate of 1 sec). the next healthiest phase according to its priority. The under voltage condition on a particular phase is indicated by the LED of the respective phase blinking at the rate of 3 sec. the entire load to the next available healthiest phase according to the priority set by the user. The over voltage condition on a particular phase is indicated by the LED of the respective phase blinking at the rate of 0.5 sec. Range Automatic Phase Selector Specification 8623 Features 130

164 Glossary Ingress Protection The IP (Ingress Protection) rating given to an enclosure states the degree of protection it offers by means of two digits. A summary of these is shown First Digit The first digit covers protection against penetration by solid objects, which includes hands and tools such as screwdrivers. At the lowest of from damage by intrusion or of a person contacting live or moving parts. At the highest, there shall be no entry of dust. Second Digit of protection against the entry of water, on a progressive scale. For example, number 1 indicates that dripping water shall have no harmful effect, and number 6, that water projected in powerful jets against the enclosure from any direction shall have no harmful effects. 0. No Protection 0. No Protection 1. Protected against solid objects up to 50 mm e.g. accidental touch by hands 1. Protected against vertically falling drops of water eg. condensation 2. Protected against solid objects up to 12 mm e.g. fingers 2. Protected against direct sprays of water up to 15 from the vertical 3. Protected against solid objects over 2.5 mm e.g. tools and wires 3. Protected against sprays of water up to 60 from the vertical 4. Protected against solid objects over 1 mm e.g. tools, wires and small wires 4. Protected against after splashed from all directions -limited ingress permitted 5. Protected against dust -limited ingress, no harmful deposits 5. Protected against low pressure jets of water from all directions -limited ingress permitted 6. Totally protected against dust. 6. Protected against strong jets of water e.g. for use on ship decks -limited ingress permitted The letter X can be used in place of the first or second digit to indicate that tests have either not been made or are not applicable. Category Of Duty The category of duty defines the basic type of circuit and switching capability of the device, and selection should be made accordingly. Utilisation Category Typical Applications AC20/DC20 Connecting and disconnecting under no-load.

(Icw) is the current the circuit breaker will withstand for the maximum short-time delay time. Preferred times are 0.05, 0.1, 0.25, 0.5 and 1.0 second. Terminology Related to SPD General Operations of SPD The Surge Protection Devices (SPD) is a device used to limit transitory overvoltage surges and to divert impulse currents away. They contain at least one non-linear component (such as varistor and/or GDT ). during normal operation (in absence of surges), SPD shall have no influence on the system to which it is applied. SPD acts as an open circuit and maintains insulation between the line and earth. when surge occurs, the SPD lowers its impedance in some nanoseconds and diverts the surge current. SPD behaves as a closed circuit, the surge voltage is short circuited. The overvoltage is limited to after surge occurrence, the SPD recovers its high impedance and behaves as an open circuit. Incoming circuit-breaker Maximum Continuous Operating Voltage (Uc/Ucpv)- The maximum continuous operating voltage Uc is the maximum r.m.s/ dc voltage which may be applied continuously to the SPD. It has to take into account the network nominal voltage Un plus the possible tolerances. Nominal discharge current (In)- This is the discharge current with 8/20 μs waveform that the Class 2 SPD is able to divert (towards earth) at least 15 consecutive times, without deteriorating. The higher it is, the longer the life of the SPD will be. Impulse current (Iimp)- The impulse current (Iimp), used in Class I test is the maximum impulse 10/350 μs current a surge protector can withstand without destruction. This test simulates the effect, of a direct lightning strike on an installation. Maximum Discharge current (Imax)- The maximum discharge current (Imax), applicable to Type 2 SPD, is the maximum impulse current 8/20 μs a surge protector can withstand without destruction. The higher the Imax is, for the same In, the safer the SPD is working, far away from its performance limits. Protection Level (Up)- The residual voltage that is measured across the terminal of the SPD when In is applied. Surge protection needs to be selected such that their voltage protection level (Up) is lower than the Follow-through current (If)- Current supplied by the electrical supply grid, which flows through the SPD following an impulse current. It is a parameter for spark-gaps and gas discharge tubes and does not concern varistors.
